참여 물질

반응 단계

A solution of 1-(4-fluorophenyl)-6-methyl-N-{[2-(trifluoromethyl)-2-oxiranyl]methyl}-1H-indazol-4-amine (1.52 g, 4.16 mmol) in dichloromethane (30 ml) was added to ethylamine (2M in tetrahydrofuran) (70 ml, 140 mmol). The reaction was stirred at room temperature overnight and then evaporated in vacuo. The crude product was purified on a 70 g silica Bond Elut cartridge using a 0-100% ethyl acetate in dichloromethane gradient over 60 mins to give the title compound (1.463 g).
